In addition, the first device 100 may exchange data with the thirddevice 300 by using a wireless communication function of the seconddevice 200. When the second device 200 receives a text message from thethird device 300, the first device 100 may also receive the text messagefrom the second device 200 and may display the text message, and thenthe user may check the text message via the first device 100 and mayprovide an answer message to the third device 300 via the second device200.

In another example, when the second device 200 receives a call requestfrom the third device 300, the second device 200 may provide the callerinformation of the third device 300 to the first device 100. In thiscase, the user may check the caller information via the first device 100and may decide whether or not to receive the call request. The user maycheck the caller information of the third device 300 via the firstdevice 100, may write a message related to call reception, and mayprovide the message to the third device 300 via the second device 200.

In yet another example, the first device 100 may provide a file storedin the first device 100 to the second device 200 via a widget window.The first device 100 may also receive content that is being executed inthe second device 200 and output the received content on its associateddisplay.

The first device 100 will be described in more detail with reference toFIG. 2.

FIG. 2 is a diagram illustrating the structure of the first device 100,according to an exemplary embodiment of the present invention.

Referring to FIG. 2, the first device 100 includes a connecting unit110, a data receiving unit 120, a widget window generating unit 130, adata output unit 140, a detecting unit 150, a data transmitting unit160, a DataBase (DB) 170, a transmitting and receiving unit 180, and acontrol unit 190.

The connecting unit 110 connects the first device 100 and the seconddevice 200. In one example, the connecting unit 110 may connect thefirst device 100 and the second device 200 via a user input in a widgetwindow that is generated by the widget window generating unit 130described below. For example, when a user selects a tethering button ofthe widget window, the connecting unit 110 may request the second device200 for the connection. Although a user input is not separately input,if the widget window is executed, the connecting unit 110 may requestthe second device 200 for the connection.

The connecting unit 110 may store the previously received accessinformation from the second device 200, which is for connection to thesecond device 200. The connecting unit 110 may first request connectionto the second device 200 and then may receive the access informationfrom the second device 200. The access information for connectionbetween the first device 100 and the second device 200 may be previouslyset in the first device 100 and the second device 200 by a user.

The data receiving unit 120 receives data from the second device 200.For example, the data receiving unit 120 may receive an address bookthat is stored in the second device 200 and may be used by the firstdevice 100 to detect a device to receive data using a widget window. Inanother example, the data receiving unit 120 may receive informationfrom the second device 200 associated with installed applications in thedevices and may also include the address book. Alternatively,information associated with applications installed in the devices may bestored in the address book.

The data receiving unit 120 may also receive caller information of thethird device 300 from the second device 200. When the third device 300requests a phone call, the data receiving unit 120 may receive thecaller information of the third device 300 from the second device 200,which may be displayed on a screen via the widget window.

In yet another example, the data receiving unit 120 may receive a textmessage via the second device 200. When the second device 200 receivesthe text message from the third device 300, the data receiving unit 120may receive the text message and device information of the third device300 from the second device 200. The device information may include atleast one of a phone number, a user identification value, and anidentification value of an application installed in the device.

Also, the data receiving unit 120 may receive content that is beingexecuted in the second device 200. For example, the data receiving unit120 may receive the content that is being executed in the second device200, in a streaming manner. In another example, when a screen iscaptured in the second device 200, the data receiving unit 120 mayreceive the captured screen of the second device 200.

The widget window generating unit 130 generates a widget window for adata exchange with the second device 200. The widget window may includea detection field for device detection that may be displayed on apre-set area of a background screen of the first device 100. A guidemessage for the device detection may also be displayed in the detectionfield of the widget window. For example, when a keyword is input via thedetection field of the widget window, a device associated with the inputkeyword may be detected.

When a file stored in the first device 100 is moved to the widgetwindow, the widget window generating unit 130 generates a filetransmission method selection window that is used to select of a filetransmission target. The file transmission method selection window mayinclude a list for selecting the target device, such as the seconddevice 200 or the third device 300 that is not connected to the firstdevice 100. For example, the file transmission method selection windowmay include a selection list such as ‘transmission to second device’,‘detection of another device’, or the like. Also, when the third device300 is selected (i.e., when ‘detection of another device’ is selected),a guide message related to a keyword input may be displayed in thedetection field of the widget window.

The data output unit 140 outputs data received from the second device200 on the first device 100. For example, when the detection field ofthe widget window is selected in response to a user input, the dataoutput unit 140 may display the address book received from the seconddevice 200 on a screen of the first device 100.

When the data output unit 140 receives the caller information from thesecond device 200, the data output unit 140 may display the receivedcaller information on the screen of the first device 100. The dataoutput unit 140 may display a message regarding an incoming call on thescreen of the first device 100. In more detail, the data output unit 140may extract a user name and a phone number of the third device 300 fromthe caller information of the third device 300, combine an extractedvalue with a predefined text, and output a guide message regardingwhether or not to accept the incoming call on the first device 100. Forexample, the data output unit 140 may display a guide message saying “Anincoming call from Tom (555-1234). Do you want to accept this call?” onthe screen of the first device 100. When the user rejects to accept theincoming call, the data output unit 140 may display a messagetransmission window for transmission of a predetermined text message onthe screen.

The data output unit 140 may output a text message that is received viathe second device 200 on the screen of the first device 100. When thefirst device 100 receives a message from the third device 300 via thesecond device 200, the data output unit 140 generates a communicationwindow for a message exchange between the first device 100 and the thirddevice 300 and displays the communication window on the screen.

The data output unit 140 may output the content that is being executedin the second device 200 on the first device 100. The data output unit140 may determine an application to execute based on content that isreceived from the second device 200 and may output the content that isbeing executed in the second device 200 using the determinedapplication. For example, when the first device 100 and the seconddevice 200 are connected to each other while a moving picture isreproduced in the second device 200, the data output unit 140 may outputcontent that is streamed from the second device 200 in real-time to thefirst device 100. In this case, application information to execute thereceived content may be previously set and stored in the first device100.

The detecting unit 150 may detect a device to receive data based on auser input via the widget window. When a user selects the widget windowand inputs a keyword to the detection field of the widget window, thedetecting unit 150 may detect a device that corresponds to the inputkeyword from the address book received from the second device 200.

In this example, the keyword input by the user may include a pre-set tagvalue and the detecting unit 150 may filter devices included in theaddress book according to the tag value. The tag value may differ fromanother tag value according to types of data transmission services thatare supported by the devices included in the address book. For example,the tag value may be a prefix value, and in this regard, a prefix ‘A’may be used to detect devices in which Twitter® is installed, and aprefix ‘B’ may be used to detect devices in which Facebook® isinstalled. Thus, when ‘A Tom’ is input to the widget window, thedetecting unit 150 may detect a device whose user name is ‘Tom’ fromamong the devices in which Twitter® is installed. In another example,when ‘B friends’ is input to the widget window, the detecting unit 150may detect a device of a user who is a friend of a user of the firstdevice 100 from among the devices in which Facebook® is installed.

The data transmitting unit 160 transmits data to the third device 300via the second device 200. The data transmitting unit 160 may providethe data to the second device 200 and may transmit the data to the thirddevice 300 by using a communication function of the second device 200.

In more detail, the data transmitting unit 160 may provide a textmessage to the third device 300 via the second device 200. When thethird device 300 is detected and selected in the first device 100 viathe widget window, the communication window for a message exchangebetween the first device 100 and the third device 300 may be generatedin the first device 100. For example, when a text message is input tothe communication window by a user, the first device 100 may transmitthe text message to the third device 300 via the second device 200.

In addition, the data transmitting unit 160 may transmit informationassociated with acceptance of an incoming call. For example, when thethird device 300 requests a phone call to the second device 200, thesecond device 200 may provide the caller information to the first device100. In this case, the first device 100 may provide information relatedto acceptance of an incoming call to the third device 300 via the seconddevice 200. For example, when a user rejects the incoming call, thefirst device 100 may provide the third device 300 with a message relatedto the rejection of the incoming call. For example, an input windowmessage may be displayed on the first device 100 and the user may inputa message saying “I'm in a meeting so I can't receive your call” intothe input window.

The data transmitting unit 160 may also transmit a file stored in thefirst device 100 to the third device 300 via the second device 200. Forexample, the user may select the file stored in the first device 100,may move the selected file to the widget window, may detect the thirddevice 300 via the widget window, and may transmit the selected file tothe third device 300 via the second device 200.

The DB 170 stores information required for the first device 100 todetect the third device 300 by using the address book stored in thesecond device 200 and also stores information required to exchange datawith the second device 200 and the third device 300. For example, the DB170 may store information about the address book that is received fromthe second device 200 and information about types of applicationscorresponding to different tag values.

The transmitting and receiving unit 180 exchanges data with the seconddevice 200 and the third device 300. The transmitting and receiving unit180 may exchange data with the third device 300 via the second device200.

In order to allow the first device 100 to detect the third device 300and exchange data with the second device 200 and the third device 300,the control unit 190 controls the connecting unit 110, the datareceiving unit 120, the widget window generating unit 130, the dataoutput unit 140, the detecting unit 150, the data transmitting unit 160,the DB 170, and the transmitting and receiving unit 180.

When the seconddevice 200 receives the text message from the third device 300, thefirst device 100 may receive the text message and device information ofthe third device 300 from the second device 200. The device informationmay include a phone number, a user identification value, and/or anidentification value of an application installed in a device.

Also, in operation S402, the first device 100 may receive content thatis being executed in the second device 200. The first device 100 mayreceive the content that is being executed in the second device 200, forexample, in a streaming manner.

In operation S404, the first device 100 outputs the widget window on itsscreen for a data exchange with the second device 200. The widget windowmay include a detection field for device detection and may be displayedon a predefined area of a background screen of the first device 100. Aguide message may be displayed in the detection field of the widgetwindow for the device detection. Referring to FIG. 4, the widget windowis output after operation S402, but may be output before operation S400or operation S402 to initiate file transfer, for example.

In operation S406, the first device 100 outputs the data that isreceived from the second device 200. When the detection field of thewidget window is selected in response to a user input, the first device100 may display an address book that is received from the second device200 on the screen of the first device 100.

When the first device 100 receives the caller information of the thirddevice 300 from the second device 200, the first device 100 may displaythe received caller information on the screen. In more detail, the firstdevice 100 may extract a user name and a phone number of the thirddevice 300 from the caller information of the third device 300, maycombine the extracted information with a predefined text, and then mayoutput a guide message requesting acceptance of the incoming call. Forexample, the first device 100 may display a guide message stating “Anincoming call from Tom (555-1234). Do you want to receive this call?”When the user rejects the incoming call, the first device 100 maydisplay a message transmission window on the screen to transmit apredetermined text message to the third device 300.

In operation S406, the first device 100 may output a text message thatis received by the second device 200 on its screen. When the firstdevice 100 receives a message of the third device 300 via the seconddevice 200, the first device 100 may generate a communication window fora message exchange between the first device 100 and the third device 300and may display the communication window on its screen.

The first device 100 may output the content that is being executed inthe second device 200. The first device 100 may determine an applicationto execute the content received from the second device 200 and mayoutput the content that is being executed in the second device 200 usingthe determined application. For example, when the first device 100 andthe second device 200 are connected to each other while a moving pictureis reproduced in the second device 200, the first device 100 may outputcontent that is streamed from the second device 200 in real-time to thefirst device 100. In this example, application information to executethe received content may be previously set and stored in the firstdevice 100.

In operation S408, the first device 100 detects a device to receive datausing the widget window based on a user input. When a user selects thewidget window and inputs a predetermined keyword into the detectionfield of the widget window, the first device 100 may detect a devicethat corresponds to the input keyword in the address book. When a filestored in the first device 100 is moved to the widget window, a messagefor guiding a keyword with respect to detection of a device to receivethe file may be displayed in the widget window.

In this case, the keyword that is input by the user may include apredefined tag value and the first device 100 may filter devices in theaddress book according to the tag value. The tag value may correspond todata transmission services that are supported by the devices in theaddress book. For example, the tag value may be a prefix valuecorresponding to a specific service or function. For example, a prefix‘A’ may be used to detect devices having Twitter® is installed and aprefix ‘B’ may be used to detect devices having Facebook® is installed.Thus, when ‘A Tom’ is input to the widget window, the first device 100may detect a device whose user name is ‘Tom’ from among the devices inwhich Twitter® is installed. When ‘B friends’ is input to the widgetwindow, the first device 100 may detect a device of a user who is afriend of a user of the first device 100 from among the devices in whichFacebook® is installed.

In operation S410, the first device 100 provides the second device 200with data that will be provided to the third device 300, such as a textmessage that is input to the first device 100, for example. When thethird device 300 is detected and selected in the first device 100 viathe widget window, the communication window for a message exchangebetween the first device 100 and the third device 300 may be generatedto allow a user to input a text message and may transmit the textmessage to the third device 300 via the second device 200.

At operation S410, the first device 100 may transmit information relatedto acceptance of an incoming call. For example, when the third device300 requests a phone call to the second device 200, the second device200 may provide the caller information to the first device 100. In thiscase, the first device 100 may provide information related to acceptanceof an incoming call to the second device 200. For example, when a userrejects the incoming call from the third device 300, the first device100 may provide the second device 200 with a message related to therejection of the incoming call. For example, an input window for aninput of a call-connection message may be displayed on the first device100 and then the user may input a message stating “I'm in a meeting so Ican't receive your call” into the input window.

In another example of operation S410, the first device 100 may transmita file stored in the first device 100 to the second device 200. When auser selects a file stored in the first device 100, the selected filemay be provided to the second device 200. For example, the user mayselect the file stored in the first device 100 by placing the file inthe widget window, may detect the third device 300 via the widgetwindow, and may provide the second device 200 with an identificationvalue of the third device 300 and the selected file.

In operation S412, the second device 200 provides the third device 300with the data received from the first device 100. For example, thesecond device 200 may provide the third device 300 a text messagereceived from the first device 100, information about a call-connection,and/or a file. In this case, the second device 200 may receive deviceinformation related to the third device 300 (e.g., a phone number, ane-mail address, or the like) from the first device 100 and may transmitthe data to the third device 300 based on the received deviceinformation.

Hereinafter, a method of detecting a device to receive data will bedescribed with reference to FIG. 5.

FIG. 5 is a flowchart of a method of detecting a device to receive data,according to an exemplary embodiment of the present invention.

In operation S500, the first device 100 and the second device 200 may beconnected to each other based on, for example, a user input via a widgetwindow of the first device 100. For example, when a user selects atethering button of the widget window, the first device 100 may requestconnection to the second device 200 to further connect to the thirddevice 300.

In operation S502, the first device 100 receives an address book fromthe second device 200. The address book received from the second device200 may include at least one of a telephone number of a device, a username of a device, an e-mail address of a device user, and an SNS accountof a device user. The address book may be used by the first device 100to detect a device to receive data using the widget window. Also, thefirst device 100 may receive information related to applicationsinstalled in the devices in the address book. Alternatively, informationrelated to applications installed in the devices may be stored in theaddress book.

In operation S504, the first device 100 receives a keyword input fordevice detection via the widget window, which may include a detectionfield for device detection and may be displayed on a predefined area ofa background screen of the first device 100. A guide message for thedevice detection may also be displayed in the detection field of thewidget window. The guide message may be displayed when a file isselected and then is moved to the widget window.

In operation S504, the first device 100 may also receive a keyword thatis input by a user via the widget window. The keyword may include a username of a device or a phone number of a device. In another example, thekeyword may include a tag value associated with a service or a function.For example, the tag value may be a prefix value and detection targetsmay differ from each other according to the tag value. For example, atag value ‘@’ may be used in detection through group names, and a tagvalue ‘#’ may be used in detection through phone numbers. In such anexample, devices in the address book may be filtered according to thetag value. For example, a tag value ‘$’ may be used to filter recentreception and transmission contact addresses of the list, a tag value‘A’ may be used to filter devices in which Twitter® is installed, and atag value ‘B’ may be used to filter devices in which Facebook® isinstalled.

In addition, the widget window may be used to search for contents andmessages that are stored in the first device 100 and the second device200. In this case, a tag value ‘!’ may be used to search for a musicfile, a tag value ‘!!’ may be used to search for a moving picture file,and a tag value ‘&’ may be used to search for a message.

The widget window may be used to detect a peripheral device connected tothe first device 100. For example, a tag value ‘̂’ may be used to detectthe peripheral device by using Digital Living Network Alliance (DLNA).

In operation S506, the first device 100 may detect the devices relatedto the input keyword in the address book. In this case, the first device100 may filter devices in which Twitter® is installed, and a prefix ‘B’may be used to detect devices in which Facebook® is installed. Thus,when ‘A Tom’ is input to the widget window, the first device 100 mayfilter the devices in which Twitter® is installed and then may detect adevice whose user name is ‘Tom’ from among the filtered devices. Also,when ‘B friends’ is input to the widget window, the first device 100 mayfilter the devices in which Facebook® is installed and then may detect adevice of a user who is a friend of the user of the first device 100from among the filtered devices.

In operation S508, the first device 100 may provide the second device200 with the data to be provided to the detected third device 300. Forexample, the first device 100 may provide the second device 200 with atext message input by the user or a file selected by the user. The firstdevice 100 may also provide the second device 200 with deviceinformation of the third device 300 to receive the data including a username, a phone number, and/or an e-mail address of a user, for example.

In operation S510, the second device 200 transmits the data receivedfrom the first device 100 to the third device 300 using the deviceinformation of the third device 300.

In this case, the keyword may include a user name of a device, a phonenumber of the device, or a tag value. For example, the tag value may bea prefix value corresponding to data transmission services that aresupported by devices included in the address book. The first device 100may filter the device by using the tag value included in the keyword.For example, a prefix ‘A’ may be used to detect devices in whichTwitter® is installed, and a prefix ‘B’ may be used to detect devices inwhich Facebook® is installed. Thus, when ‘A Tom’ is input to the widgetwindow, the first device 100 may filter the devices in which Twitter® isinstalled and then may detect a device whose user name is ‘Tom’ from thefiltered devices. When ‘B friends’ is input to the widget window, thefirst device 100 may filter the devices in which Facebook® is installedand then may detect a device of a user who is a friend of the user ofthe first device 100 from the filtered devices. The first device 100selects at least one of the detected devices as a transmission target inthe address book that is received from the second device 200.

In operation S614, the first device 100 may generate the messagetransmission window with respect to the device detected in operationS612 and may insert the file into the generated message transmissionwindow.

However, whether or not to display the file transmission methodselection window on the first device 100 may be decided according to astate of the second device 200. For example, when the messagetransmission window is displayed on the second device 200, the firstdevice 100 may not display the file transmission method selectionwindow.

Display of the file transmission method selection window on the firstdevice 100 may be decided according to a state of the first device 100.For example, when a message transmission window is displayed on thefirst device 100, the first device 100 may not display the filetransmission method selection window. Also, the first device 100 mayinsert the selected file into the message transmission window displayedon the first device 100.

In operations S616 and S618, the first device 100 provides the selectedfile to the third device 300 via the second device 200. In such anexample, the third device 300 may be the device that is selected inoperation S612.

Hereinafter, a method of performing communication between devices willbe described with reference to FIG. 10.

FIG. 10 is a diagram illustrating a method of performing communicationbetween devices, according to an exemplary embodiment of the presentinvention.

Referring to FIG. 10, the first device 100 may use a wirelesscommunication function of the second device 200 via tethering. Forexample, the first device 100 may be connected with the second device200 via Wireless Fidelity (Wi-Fi) communication. Also, the first device100 and the second device 200 may be connected to each other by using adifferent wireless communication service such as a Third Generation (3G)mobile communication or the Fourth Generation (4G) mobile communication.

In this case, a tethering function of the second device 200 may beactivated in response to a user input in a widget window in the firstdevice 100. For example, when a predetermined region is selected in thewidget window displayed in the first device 100, the first device 100may request the second device 200 for activation of the tetheringfunction. That is, when the widget window is active in the first device100, the first device 100 may request the second device 200 for thetethering function.

Also, the first device 100 and the second device 200 may exchange accessinformation for communication when the tethering function is requested.

For example, a widget window application to perform device detection anddata transmission using a widget window may be executed in the firstdevice 100. In this example, the first device 100 and the second device200 may be connected to each other by using the widget windowapplication. Also, a widget window agent in the widget windowapplication that may be executed when a power of the first device 100 isON and may execute the widget window in the first device 100 when aperipheral device for connection exists at a same Access Point (AP) asthat of the first device 100. The widget window application may detectthe second device 200 and connect the first device 100 and the detectedsecond device 200. In more detail, the widget window application maydetect the second device 200 that is a peripheral device of the firstdevice 100 and transmit an authentication code to the detected seconddevice 200. The second device 200 may confirm the authentication codeand perform Wi-Fi communication configuration for connection to thefirst device 100. Also, the second device 200 may provide the firstdevice 100 with an Internet Protocol (IP) value and a verifiedauthentication code. The widget window application may authenticate thedetected second device 200 to connect the first device 100 and thesecond device 200. After the authentication is performed between thefirst device 100 and the second device 200, the first device 100 and thesecond device 200 may be connected to each other without separateauthentication.

In another example, the first device 100 and the second device 200 maybe connected to each other by using a Universal Serial Bus (USB) cable.In this example, the widget window application of the first device 100may execute the widget window on a screen of the first device 100 andrequest the second device 200 to execute a widget window application ofthe second device 200. Also, when the USB connection between the firstdevice 100 and the second device 200 is disconnected, the first device100 and the second device 200 may be re-connected to each other viaWi-Fi communication.

Hereinafter, an address book will be described with reference to FIG.11.

Referring to FIG. 11, the address book includes a speed-dial field 90, auser field 91, a phone number field 92, a group field 93, a device field94, and an application field 95.

Speed-dials corresponding to phone numbers are recorded in thespeed-dial field 90 and user names corresponding to the phone numbersare recorded in the user field 91. The phone numbers are recorded in thephone number field 92 and group names of the user are recorded in thegroup field 93. In the address book, types of devices corresponding tothe phone numbers are recorded in the device field 94. For example,device names such as ‘Galaxy S3’ and ‘I-Phone’ may be recorded in thedevice field 94. Names of applications that are installed in the devicesare recorded in the application field 95. For example, names ofmessenger applications such as Twitter® and Facebook® may be recorded inthe application field 95. The address book may be directly provided fromthe second device 200 to the first device 100 or may be indirectlyprovided from the second device 200 to the first device 100 via aseparate server (not shown), and the first device 100 may detect adevice to receive data using the address book.

Also, prefixes may match with names of the devices recorded in thedevice field 94 and the names of applications recorded in theapplication field 95, respectively. Thus, when a user inputs a keywordfor device detection, the user may also input a predetermined prefix tofilter some of the devices by using the input prefix and performdetection with respect to the filtered devices.

Hereinafter, an example of device detection for data transmission by thefirst device 100 will be described with reference to FIG. 12.

FIG. 12 illustrates an example of device detection for data transmissionby the first device 100, according to an exemplary embodiment of thepresent invention.
